Victory tale about butler (5)
I believe the answer is:
valet
'butler' is the definition.
(thesaurus)
'victory tale about' is the wordplay.
'victory' becomes 'v'.
'about' is an anagram indicator.
'tale' is an anagram of 'alet'.
'v'+'alet'='VALET'
(Other definitions for valet that I've seen before include "Gentleman's assistant" , "dresser" , "Gentleman%u2019s gentleman" , "Man's personal attendant" , "Gentleman's attendant" .)
